Problembeschreibung

Ethereal 0.10.13 is now available fixing a number of security
vulnerabilities in various dissectors:

- the ISAKMP dissector could exhaust system memory
- the FC-FCS dissector could exhaust system memory
- the RSVP dissector could exhaust system memory
- the ISIS LSP dissector could exhaust system memory
- the IrDA dissector could crash
- the SLIMP3 dissector could overflow a buffer
- the BER dissector was susceptible to an infinite loop
- the SCSI dissector could dereference a null pointer and crash
- the sFlow dissector could dereference a null pointer and crash
- the RTnet dissector could dereference a null pointer and crash
- the SigComp UDVM could go into an infinite loop or crash
- the X11 dissector could attempt to divide by zero
- if SMB transaction payload reassembly is enabled the SMB dissector
could crash (by default this is disabled)
- if the "Dissect unknown RPC program numbers" option was enabled, the
ONC RPC dissector might be able to exhaust system memory (by default
this is disabled)
- the AgentX dissector could overflow a buffer
- the WSP dissector could free an invalid pointer
- iDEFENSE discovered a buffer overflow in the SRVLOC dissector

The new version of Ethereal is provided and corrects all of these
issues.

Update:

An infinite loop in the IRC dissector was also discovered and fixed
after the 0.10.13 release. The updated packages include the fix.
